Chemical Reactions and Equations Chemical Reaction: The transformation of chemical substance into another chemical substance is known as Chemical Reaction. For example: rusting of iron‚ setting of milk into curd‚ digestion of food‚ respiration‚ etc. In chemical reaction new substance is formed which is completely different in properties from the original substance‚ so in a chemical reaction chemical change takes place. Following are the signs of chemical reaction: (a) Change of state of substance

Physical Science I have learned from my twenty years of service in the U.S. Air Force‚ significant background knowledge of the history of the space shuttle. In September 1969‚ two months after the first manned lunar landing‚ a Space Task Group appointed by the President of the United States to study the future course of U.S. space research and exploration made the recommendation that "…the United States accept the basic goal of a balanced manned and unmanned space program. To achieve this goal‚

Chemistry Summary The particle theory: 1. Matter is made of tiny particles 2. Particles of matter are in constant motion 3. Particles of matter are held together by very strong electric forces 4. There are empty spaces between the particles of matter that are very large compared to the particles themselves. 5. Each substance has unique particles that are different from the particles of other substances 6. Temperature affects the speed of the particles. The

1) Segementation(2*2 matrix) and Targeting Segmenting the Dominite market by end-use applications of cermaic tile and paint by large and small-to medium comapnies 2) Sales Organization changes: Dominite is currently trying to sell to both large and small companies. It is economical in the long run to sell to large customers directly and to small companies through a agents or distributors. In the future to sell and to service large customers Dominite should setup a key account program.

Lab #5: Refraction of Light Theory: Refraction can be defined as the bending of a wave when it enters a medium which causes it to have some reduced speed. In terms of light‚ refraction occurs when the ray passes through some medium which slows its speed; such as water or glass. In this instance the ray tends to bend towards the normal of the medium. The amount of bending or refraction which occurs can be calculated using Snell’s Law (). Objective: To measure the index of refraction of Lucite

Q_1 From the Exhibit 4‚ U.S. Frasch Sulphur Industry Prices and Profitability‚ 1940-1967‚ we can get the information about the variations in the return on invested capital earned by the industry over the several decades. In sulphur industry‚ the return on invested capital was around 15% from 1940 to 1945. From 1946‚ rate of return began to increase dramatically‚ starting from 16.2 %( 1945)‚ and reached 33.8% in 1950. This high rate of return kept for couples of years (1951-1955)‚ ranging from 29%
